This reinsurance coverage dispute returns to us following a remand. Defendant-Appellee Seguros La República, S.A. (“Seguros”) issued 26 facultative certificates reinsuring risks underwritten by American Centennial Insurance Company (“ACIC”). ACIC’s successor, Plaintiff-Appellant British International Insurance Company Limited (“BIIC”), sued Seguros for pro rata reimbursement of sums paid by ACIC on behalf of the underlying insureds and for declaratory judgment expenses incurred by ACIC in coverage disputes over the underlying contracts of insurance. The district court entered a default judgment in favor of BIIC in the amount of $11,801,024.98. We affirmed in part, and in part vacated and remanded.
See British Int’l Ins. Co. v. Seguros La República, S.A.,
On remand, the district court granted summary judgment in favor of Seguros on the issue of declaratory judgment expenses, and entered final judgment on Au *80 gust 13, 2001. BIIC appeals from so much of the judgment as denies declaratory judgment expenses. 1
BACKGROUND
Between 1977 to 1980, Seguros issued 26 facultative certificates to ACIC, BIIC’s predecessor in interest. Essentially identical language in each certificate provides that Seguros will indemnify BIIC (up to a specified amount) “[o]n [BIIC’s] interest as insurer under” a specified insurance contract issued to a specified insured. 2 The following “Reinsurance Clause” is attached to each certificate:
This Certificate of Reinsurance is subject to the same risks, valuations, conditions, endorsements (except changes of location), assignments and adjustments as are or may be assumed, made or adopted by the reinsured, and loss, if any, hereunder is payable pro rata with the reinsured and at the same time and place ....
Following Seguros’ refusal to pay BIIC’s reinsurance claim, BIIC commenced this diversity action in April 1990. BIIC sought (1) a judgment against Seguros for breach of contract, account stated, and monies due and owing, and (2) a declaration that Seguros is obligated to pay accounts that come due under the facultative certificates in the future. Seguros failed to post pre-answer security as required under New York Insurance Law § 1213(c)(1)(A), and on May 18, 1999, the district court entered a default judgment in favor of BIIC in the amount of $11,801,024.98.
On appeal, our opinion rejected Seguros’ argument that section 1213(c)(1)(A) violated constitutional due process.
See British Int’l Ins. Co.,
On remand, the district court granted summary judgment in favor of Seguros.
See British Int’l Ins. Co. v. Seguros La, Republica, S.A.,
The district court also rejected BIIC’s argument that the follow-the-fortunes doctrine — which,
inter alia,
bars a reinsurer’s challenge to a good faith settlement reached by its reinsured on an underlying claim — should be extended to require a reinsurer to pay the reinsured’s expenses in litigation concerning the underlying insurance coverage.
Id.
at **2-3,
BIIC now appeals on the grounds (1) that the facultative certificate is ambiguous; (2) that then-prevailing custom in the industry required the reinsurer to pay a pro rata share of the cedent’s expense in resisting coverage; and (3) that such payment is compelled by the reinsurance doctrine requiring the reinsurer to follow the fortunes of the cedent. 3
DISCUSSION
“We review a district court’s grant of summary judgment
de novo.” Young v. County of Fulton,
I
BIIC does not argue that any provision of the facultative certificates expressly requires pro rata payment of declaratory judgment costs. On appeal, as below, BIIC relies on the provision of the Reinsurance Clause that Seguros is “subject to the same risks, valuations, conditions, and endorsements ... as may be assumed or adopted by [BIIC], and loss, if any hereunder,” (emphasis added), and identifies the word “risks” as the source of ambiguity that could cover declaratory judgment expenses. BIIC emphasizes the cumulative force of the word “risks” in the context of the words that follow it: “valuations, conditions, and endorsements ... as may be assumed or adopted by [BIIC], and loss, if any hereunder.” Arguing that the provision as a whole is ambiguous, BIIC contends that this ambiguity must be resolved by resorting to industry custom. This is an expansion of the argument made in the district court, but we deem that it is within the scope of that argument and is therefore preserved.
The parties agree that New York law governs this diversity case; their “consent concludes the choice of law inquiry.”
Am. Fuel Corp. v. Utah Energy Dev. Co.,
“Under New York law, a written contract is to be interpreted so as to give effect to the intention of the parties as expressed in the unequivocal language they have employed.”
Cruden v. Bank of N.Y., 957
F.2d 961, 976 (2d Cir.1992). “Where ... the contract is clear and unambiguous on its face, the intent of the parties must be gleaned from within the four corners of the instrument, and not from extrinsic evidence.”
Rainbow v. Swisher,
BIIC contends that the Reinsurance Clause language — subjecting Seguros “to the same risks, valuations, conditions, and endorsements ... as may be assumed or adopted by [BIIC], and loss, if any hereunder”- — -read as a whole, is incapable of being understood without resort to industry custom: “[t]he only way to understand this phrase is to look at the custom and practice of the reinsurance industry at the time [Seguros] drafted the Facultative Certificates.” Appellant’s Br. at 22. A party relying on ambiguity is normally obligated to show that a word, phrase, or provision “could suggest more than one meaning.”
Alexander & Alexander Servs.,
The leading case on the use of industry custom in a reinsurance dispute
*83
over declaratory judgment expenses is
Affiliated FM Insurance Co. v. Constitution Reinsurance Corp.,
Affiliated FM is most easily distinguished here on the basis that the word “expenses” — held to be ambiguous in Affiliated FM- — does not appear in the Seguros facultative certificates. More generally, Affiliated FM supports the view that a party seeking to establish ambiguity must articulate multiple meanings that the contract language will sustain.
Similarly, in
Employers Reinsurance Corp. v. Mid-Continent Casualty Co.,
BIIC argues for the first time on appeal that the word “loss” is ambiguous because it could include declaratory judgment expenses. This argument was not considered by the district court and we decline to exercise discretion to hear it on appeal.
See Mattel, Inc. v. Barbie-Club.com,
We conclude that BIIC has failed to articulate any ambiguity in the terms of these facultative certificates.

Seguros contends, and the district court agreed, that the certificates unambiguously limit reinsurance coverage to the risks specified in BIIC’s policies with its policyholders. BIIC argues that even in the absence of ambiguity on that score, industry custom and practice may be used to supplement the terms expressed in the contract. 5 BIIC’s brief does not formulate the circumstances in which a term may be thus implied, or why this case requires that result; however, we conclude that the record evidence of custom and practice is insufficient to raise the legal issue.
“[T]he burden of proving a trade usage has generally been placed on the party benefiting from its existence.”
Putnam Rolling Ladder Co. v. Mfrs. Hanover Trust Co.,
BIIC submitted two affidavits in support of its allegation of a trade usage. William N. Edwards, a supervisor and manager in the claims department of the American Re-Insurance Company (“American Re”) from 1974 until 1983, testified that: he was “not aware of American Re ever refusing to pay its share of declaratory judgment expenses ceded to it by its reinsureds”; he “never questioned whether declaratory judgment expenses should be treated differently than any other expenses submitted for payment by a cedent under American Re’s reinsurance contracts”; and he was unaware prior to 1983 of anyone holding a contrary view. The practice of one company, however, is generally insufficient to establish a trade usage.
See, e.g., Encyclopedia Britannica, Inc. v. S.S. Hong Kong Producer,
William Gilmartin, who has 51 years of experience in the insurance and reinsurance industries, affirmed that between 1976 and 1983, “[i]t was the custom and practice for reinsurers to pay [their rein-sureds’ declaratory judgment] expenses due to the common interest they shared with their reinsureds arising from the defense or prosecution of a declaratory action.” Gilmartin did not aver, however, that these (unnamed) reinsurers always and invariably paid these costs,
see, e.g., Hutner,
BIIC also failed to adduce evidence that Seguros either actually knew of the alleged custom, or that the practice of reinsurers’ paying declaratory judgment expenses was “so notorious” in the industry that Seguros must have been aware of it.

*85 III
Finally, BIIC contends that Seguros owes its pro rata share of BIIC’s declaratory judgment expenses by operation of the follow-the-fortunes doctrine. That doctrine binds a reinsurer to accept the cedent’s good faith decisions on all things concerning the underlying insurance terms and claims against the underlying insured: coverage, tactics, lawsuits, compromise, resistance or capitulation. “Under the ‘follow the fortunes’ doctrine, a reinsurer is required to indemnify for payments reasonably within the terms of the original policy, even if technically not covered by it. A reinsurer cannot second guess the good faith liability determinations made by its reinsured .... ”
Christiania Gen. Ins. Corp. v. Great Am. Ins. Co.,
Because the doctrine “simply requires payment where the cedent’s good-faith payment [to its insured] is at least
arguably within the scope of the insurance coverage that was reinsured,” Mentor Ins. Co. (U.K) v. Brannkasse,
CONCLUSION
The judgment is affirmed.
Notes
. Seguros has not cross-appealed from the portion of the judgment finding that BIIC presented sufficient evidence of the disputed $52,987.22, and its decision is unsurprising. After the summary judgment proceedings, BIIC informed the court that the disputed amount was incurred in declaratory judgment proceedings, and thus Seguros is not obligated to pay that amount based on the court’s ruling that declaratory judgment expenses are not covered by the facultative certificates.
. For example, one certificate memorialized Seguros' obligation to indemnify BIIC (up to a specified amount) "[o]n [BIIC's] interest as insurer under its Umbrella liability policy] ... issued to Dow Chemical Co.”
. We are aware that the question of whether an ambiguity exists is answered from the point of view of someone who,
inter alia,
“is cognizant of the customs, practices, usages and terminology as generally understood in the particular trade or business.”
Alexander & Alexander Servs.,
. BIIC also argues — without basis — that certain language in the district court’s Opinion and Order "implicitly acknowledges an ambiguity" in the facultative certificates.
. We conclude that this issue is properly presented on appeal, though that is a close question. BIIC argued to the district court that Seguros is liable for BIIC's declaratory judgment expenses because of the purported industry custom of reinsurers paying these expenses. Although there is no evidence that BIIC specifically framed the issue for the court as one of adding contract terms, we determine that the argument was sufficiently before the district court.
. By resolving the issue on this ground, we have no need to consider Seguros’ argument *85 that adding a term to the certificate requiring the payment of declaratory judgment expenses would vaiy and alter the express terms of the reinsurance contract.
